SPECIFICATION forming part of Letters Patent No. 740,501, dated October 6, 19.03.

Application filed November 12, 1902. Serial No. 131,007. (No model.)

To a/ZZ whom it Wwf/y con/cern:

Be it known that I, ARTHUR E. WHITNEY, a citizen of the United States, residing at Chicago, in the county of Cook and'State of Illinois, have invented certain new and useful Improvements in Hot-Air Feeders for Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. v

My invention relates to improvements in a device used in connection with a cooking stove or range for feeding heated air to the re-pot to aid combustion of the fuel, and thereby increasing its-heating power.

The object of my invention is to provide a simple and inexpensive device of this kind which may be applied to any cookingsstove of ordinary construction, and it is adj ustable,

so that it may be adapted to the varying di` mansions of such stoves. v In the accompanying drawings, Figure lis a plan view of Aa cooking-stove, part of theAV top plate being removed to show my invention. Fig. 2Ais a longitudinal section of the stove, my invention being shown in elevation and partly in section.l Fig. 3 is a perspective view of a portion of the air-tube.

Referring speeically to the drawings, 6Y

indicates the top plate of a cooking-stove, having lids 6a, as usual. dieated at 7, the grate at 8, the ash-pit at 9, the flame-chamber at l0, and the smoke-flue at 11. These and the other parts of the stove are well' known and may beof the usual or preferred construction, the particular construction of the stove being immaterial to my invention and not affecting the operation of the same, in which respect my invention is .bustion The tire-pot is in-.

formed, which are closed at their respective ends and provided with downwardly-directed discharge-openings 12C. The tube extends obliquely across the flame-chamber, passing betweentthe front lids in order not to interfere with the same, and communicates with an opening 13 in the lid, which opening mayv be opened or closed by a register 14.. The lid referred to is preferably one of the rear ones in order that. the tube may extend through the entire length of the llame-chamber, and thus receive the greatest amount of heat from the same. It is also removed from the walls of the flame-chamber, so thatvall sides of it are exposed 'to the dames.

In order that the tube may be accommodated to dierent-sized stoves, I form a teleseoping joint in the same, as at 12d and 12e, in the horizontal and vertical portions, re'- spectively. By this means the tube can be lengthenedor shortened, asydesired, to suit dierent lengths of stoves and diierent depths of fire-pots.

In 'operation the register is opened. The air then enters the tube and' is rapidly heated therein, and inpassing out through the Aopenings 12C it combines with the fuel in the tire-pot, and thereby greatly promotes com- Having thus described my invention, what is claimed as new, and desired to be secured by Letters Patent, is-f- The combination with a stove, of a lid having an'opening therein, a vertically and horizontally extensible air-feeding tube extending `from said opening through the due-chamber removed from the walls thereof, into the repot, and having laterally-extending branches parallel to the grate and in close proximity thereto, provided with downwardly-directed discharge-openings, and a register to open and close the opening in the lid, substantially as described. In testimony whereofl I affix my signature in presence of two witnesses.

ARTHUR E. WHITNEY.
